As to structure, there is hardly anything that justifies its ex- clusion from the genus Oanis. Garrod, however, mentions the unusually large size of the Spigelian lobe of the liver. Wortman and Malkens2 have instituted a genus JSTotJiocyon for Dr. Mivart's species C. urostictus* and O. yarwidens, which are both South American forms. The genus Otocyon contains but one species, O. megalotis, an African species, ranging pretty widely in that continent (from the Cape to Somaliland, in sandy districts), and sometimes con- fused with the Fennec on account of its long ears. Its prin- cipal structural difference from other Dogs is that there is an additional molar in each jaw, the molar formula being thus M ^ or even -J. Moreover the carnassial teeth are not so pro- nounced, and Professor Huxley laid especial stress upon the 1 The relationship between tlie Canidae and the Procyonidae must not be lost sight of in considering this point of external likeness. 8 Bull. ^nicr.
